Car is driving at the rate of 58km per hour. How much time will it take to drive for distance of 32 miles? REASON?
1 answer:
As we are given
Car is driving at the rate of 58km per hour
First we will have to convert it into miles per hour
As we know that 1 km per hour =0.621371 miles per hour
So we can say 58km per hour=58*0.621371 miles per hour=36.0395 miles per hour
We are supposed to find -"How much time will it take to drive for distance of 32 miles"
As we know that
Distance=Speed*Time

Answer:
• zero: -4, -4/3, 7
• positive: -4 < x < -4/3 . . . or 7 < x
• negative: x < -4 . . . or -4/3 < x < 7
Step-by-step explanation:
Zeros of the function are at x=-4, -4/3, +7. These are the values that make each of the individual factors be zero. For example, x-7=0 when x=7.
The function will be negative for x-values left of an odd number of zeros. It will be positive for x-values left of an even number of zeros (including left of no zeros, which is to say right of all zeros). This is because the sign of the factor giving rise to the zero changes for x-values on either side of that zero. (This is not true for zeros with even multiplicity, as the sign does not change at those.)
